Measure how fast your internet connection is right now: download, upload, latency and jitter. The test takes about 15 seconds.
Measured against our server in Germany. The result depends on the route there, your Wi-Fi and other devices on your network. The test uses up to 260 MB of data, so use it sparingly on mobile data.
Download is how fast data reaches you, for example when streaming. Upload is the other direction, important for video calls and backups. Latency is the server's response time and jitter its variation; both matter for gaming and calls.
The most common cause is Wi-Fi: walls, distance and neighbouring networks slow it down. For comparison, measure with a network cable directly at the router and with no other devices active. In the evening more users also share your provider's lines.
It is a good indication, not an expert report. We measure against a single server; it cannot fully load very fast connections from about 1 Gbit/s. For a complaint to your provider, regulators usually require their own official measurement.
